The main objects of this .inve'ntion'are o a i a Inrst, to provide'm a papercutter an improved means for squaring the sheets sothat theymay be accurately out. I Second, to prov dea structure having these advantages which. is very rapidly manipue lated to gage the sheets so that'they are cut.

to true rectangular form Objects pertaining to details and economies of my invention will definitelyappear from the description to follow. defined in theclaims, a r I A structure embodying the features of my invention is clearly illustrated in the accom panying drawing, inwhich:

Referring to the drawing, 1 represents the frame of the machine in which the cutter head 2 is mounted for vertical reciprocating movement. The details of the actuating means: for the cutter head form no part of this invention and therefore are not further described.

The table 3 projects at one side of the maj.

chine for the arrangement ofthe sheets thereon, the sheets being conventionally illustrat ed at/l. The table has a longitudinal sl0t,5 therein in which the gage 6 is adjustably mounted. Y This gage 6 is also of standard type and is disposed withits-face parallel to the cutter 7 8 for the gage bar- 9. This support 8has an angled face, the horizontal portion 10 of the facebeing in the plane of the surface of the .tableso that the gage bar 9 reeiprocates or slides on this horizontal faceand on the face of the table. I g F A retainingplate 11 is mounted on the support 8 to overlap the upper edge of the gage bar. The gage bar is adjustably supported by means of the screws 12and 13 which are arranged in pairs, the screws of the pairs being oppositely threaded. These screws are threaded into the gage bar at 14 and are secured in their adjusted positionsbymeans of the lock nuts 15. The outer ends of the screws are slotted at 24 so that the screws may The'invention isv p in spaced relation to the support 8 by means chine,

The screws are provided withp'inions 1 6 which have threaded. engagement with the screws, the rack bar 17 being arranged be j tween the pinions so that by reciprocating the bar the screws are simultaneously adjusted; The pinions are supportedagainst outward,

I have illustrated and described my-improvements in an embodiment which has proven' very satisfactory. I have not at, tempted to illustrate modifications and adaptations which I contemplate as Ibelieve the disclosure made will enable those skilled in the art to embody or adapt' my improvements as may be desired. 7 v

Having thus described my invention what I 'claimxasfnewiand desire to secure by Let ters Patent is:

1. Ina structure of the class described inj eluding a cutter and a table operatively' associated therewith, the combination of a gage f support mounted at the side ot the table and having an angled face, the horizontal portion of which is disposed in a plane flushwith the surface of the table, a gage barslidably. mounted onsaid support, adjusting screws slidable in said support and adjustably connected to said gage bar, adjusting pinions having threaded engagement with said screws,a rack-bar coacting with said pinions whereby they are simultaneouslyrotated as; the rack bar is reciprocated, anda second gage adjustably mounted onsaid table at gage and parallel re- 2. In a structure of the class described ini eluding acutter anda table operatively associated therewith, the combination; of a gage support mounted at the side of the table, a gage bar, adjusting screws slidableinsaid engagement with said screws, a rack bar'coacting with said pinions whereby they are simultaneously rotated as the rack bar is reciprocated, and a second gage adjustably mounted on said table at right angles to said gage and in parallel relation to said cutter.

3. In a structure of the class described, the combination of a table, a gage supportmounted at the side of the table and having an angled face, the horizontal portion of which is disposed in a plane flush with thesurface of the table, a gage bar slidably mounted on said support, pairs of oppositely threaded adjusting screws slidable in said support and connected to said gage bar, pairs of adjusting pinions having threaded engagement with said screws, a rack bar arranged between said pairs of pinions whereby they are simultaneously rotated as the rack bar is reciprocated, and a second gage adjustably mounted on said table at right angles to said gage bar.

4. In a structure of the class described, the combination of a table, a gage support mounted at the side of the table, a gage bar, pairs of oppositely threaded adjusting screws slidable in said support and adjustably connected to said gage bar, pairs of adjusting pinions havin threaded engagement with said screws, a rack bar arranged between said pairs of pinions whereby they are simultaneously rotated as the rack bar is reciprocated, and a second gage adjustably mounted on said table at right angles to said gage bar. 5. In a structure of the class described, the combination of a table, a gage support mounted at the side of the table, a gage bar, pairs of oppositely threaded ad'usting screws slidable in said support and adjustably connected to said gage bar, pairs of adjusting pinions having threaded engagement with said screws, and arack bar arranged between said pairs of pinions whereby they are simultaneoalsly rotated as the rack bar is reciprocate 6. In a structure of the class described, the

combination of a table, a gage sup ort mounted at the side of the table, a gage ar slidably mounted on said support, adjusting screws adjustably connected to said gage bar, adjusting members having threaded enga ement with said adjusting screws, means or simultaneously actuating said adjusting members, and a second gage member adjustably mounted on said table at right angles to said gage bar.
